Synthesis and Antimicrobial Activities of Complexes of Cu(II) and Ni(II)-pyridine-2-aldoxime & Alkaline Earth Metal Salts

摘要

The copper(II) and nickel(II)-pyridine-2-aldoxime, M3(pyox)_2 have been used as a complex ligand for the synthesis of a number of oxygen bridged complexes of the general formula M_a(pyox)_2·M_bL2, M_a(pyox)_2 acting as a bidentate complexing agent, coordinating through two oximino oxygens to alkaline earth metal salt (M_bL2) (where M_b = Mg, Ca, Sr or Ba; L = deprotonated 8-hydroxyqumoline or 1-nitroso-2-naphthol). The strucure has been substantiated by infrared, electronic absorption spectra and magnetic moment measurements, Most of the compounds have shown significant activity against E. coli, S. aureus and C. albicans.
